Nobody inside the hall heard it at first.

They were too loud. The argument in the far corner had gotten worse, two men almost chest to chest over something about the gate, whether to open it for more people or keep it shut. A woman was trying to get someone on a phone that hadn’t had signal for forty minutes. Three kids near the back wall were crying in shifts, one stopping long enough for another to start.

Tobi heard it.

He put his hand on his mother’s arm. "Stay here."

"Tobi—"

He was already moving to the gate.

It was a solid metal thing, old, hinged on the left, with a sliding bolt and a small gap at eye level if you stood on your toes. He stood on his toes and looked through.

The street was empty.

Then it wasn’t.

It came from the west end of the road, moving slowly, which was somehow worse than the fast stuttering movement of the smaller ones. It was big. Not enormous, not building-sized, nothing like the shapes behind the crack in the sky. But it was big the way a horse is big when you’re standing next to one and you suddenly understand the weight of it. Low-slung body, six limbs, the front two longer than the rest, dragging along the ground with each step. Its head was a flat wedge shape with no obvious features except a cluster of darker spots at the front that caught the firelight wrong.

Behind it, like it was herding them, four of the small clicking creatures moved in a loose formation.

Tobi stepped back from the gate.

The man who’d been trying to organize the room was suddenly next to him. Fifties, broad, a blue security guard uniform. Name tag said FESTUS. He looked through the gap himself.

"Generator," Tobi said quietly. "Turn it off."

Festus looked at him. "That kills our lights."

"It also kills the noise. That thing is moving toward us. The lights aren’t helping."

Festus held his gaze for a moment. Then he moved to the back of the hall. Ten seconds later the generator cut out and the hall went dark except for phone screens and one battery lantern someone had in a bag.

The room went quiet when the lights died. Fear does that. Unifies people temporarily.

Tobi looked through the gap again.

The large creature had stopped in the middle of the road. It was twenty meters away. Its head moved in a slow arc, those dark spots sweeping across the gate, across the wall, pausing.

One of the small ones clicked.

The large creature’s head turned toward the hall.

Tobi stopped breathing.

It took two steps forward.

Behind him he heard someone in the hall start to say something and someone else hiss at them to shut up, and the whispering scuffle of it was too loud, too loud, and Tobi turned and found the source with his eyes and shook his head once, hard.

Silence.

He looked back through the gap.

The creature was fifteen meters away now. Still moving slowly. The small ones had spread out slightly, flanking formation on either side.

His system pulsed.

[THREAT ASSESSMENT: HOSTILE ENTITIES APPROACHING]

[HOST OPTION: EVACUATE REAR EXIT]

[HOST OPTION: HOLD POSITION]

[HOST OPTION: ENGAGE]

[NOTE: REAR EXIT LEADS TO OPEN GROUND. RECOMMENDED AGAINST.]

He looked back at the room. Forty-something people. His mother near the far wall with her hand on Mrs. Adeyinka’s shoulder. Chike still on the floor, watching him. Children. An old man with an oxygen tank. A woman who was clearly pregnant, maybe seven months, sitting against the wall with her hands on her stomach.

No rear exit that meant anything.

He looked at Festus. "What do you have."

Festus understood the question immediately. He was that kind of person. "Two security batons. A machete I keep in my locker. That’s my hall."

"Get the machete."

Festus went.

Chike stood up from the floor. He still had the fire extinguisher. He looked at Tobi with an expression that said he already knew what was happening and wasn’t happy about it and was going to do it anyway.

Tobi’s mother appeared at his elbow.

"Don’t," he said.

"I’m not going to argue with you," she said. "I’m a nurse. If you get hurt you need me close."

"Mom—"

"Stop wasting time."

Festus came back with the machete. Old thing, worn handle, blade that had been sharpened recently by the look of it. He handed it to Tobi without ceremony.

The deep vibration outside was getting closer. Tobi could feel it in his back teeth now.

He looked at the gate. Then at the people behind him. Then at the small gap under the gate where the ground was visible.

Two of the small ones were already at the gate.

The bolt wasn’t going to hold forever. He could see the gate shuddering already, small impacts, testing.

"When it comes through," he said to Festus and Chike, keeping his voice completely flat, "the big one is mine. You two handle whatever else gets inside. Keep everyone in the back corner, keep the kids behind the adults."

"You’ve done this before?" Chike asked.

"No."

Chike made a sound that wasn’t quite a laugh.

The bolt gave.

The gate swung open and the two small ones poured through and Festus met the first one with the security baton and the crack of it hitting something solid was very loud in the enclosed space and people screamed and Tobi was already moving past both of them and through the gate because the big one was right there and he needed it away from the entrance.

He came through the gate at a run and the creature’s head snapped toward him immediately.

Up close it was worse. The dark spots that he’d thought might be eyes weren’t eyes. They were holes, small and perfectly round, and he could feel something coming out of them, not air, not heat, just wrongness, a pressure at the front of his skull like the beginning of a headache.

It lunged.

He threw himself left and the front limb came down where he’d been standing and cracked the pavement and he felt the impact through his feet. He came up and drove the machete into the side of the limb before it pulled back. The blade bit. The creature made a sound, not the clicking, something lower, and pulled the limb back hard and nearly took the machete with it.

He yanked the blade free.

Dark fluid on the ground. Not blood. Something darker.

It turned toward him. Faster now. Less patient.

The pressure behind his eyes got worse.

He shook his head against it and moved right, keeping moving, not standing still because standing still meant that weight came down on him and he’d seen what it did to pavement. The creature tracked him, turning, those front limbs dragging. It was reading him. Adjusting.

He stopped adjusting with it and went straight at it instead.

He got under the sweep of the front limb and drove the machete up and in and felt it connect with something that gave resistance and then gave way. His whole arm rang with the impact. The creature’s weight shifted above him and he rolled out from under it and came up on the other side.

It was slower now. One of its front limbs wasn’t tracking right.

He hit it twice more. Fast. Not elegant. Not anything like a fight scene. Just force and motion and the specific desperate energy of a person who had no other option.

The creature went down on its front.

Then it stopped.

He stood over it, breathing in ragged pulls, machete still in his hand, dark fluid on his shirt and his hands and the pavement all around him. His legs were shaking. His right shoulder felt like he’d hit a wall with it. The pressure behind his eyes faded slowly, like a radio being turned down.

He looked at his hands.

The fluid was already soaking into his skin. Not spreading, not burning. Just absorbing. Like he was dry ground and this was rain.

He had no idea what that meant.

The system blazed white in his vision.

He stared at it.

Inside the hall, Chike was saying something, and Festus was answering, and he could hear his mother’s voice cutting through both of them giving instructions in that tone that people always listened to. The small ones were down. Everyone was alive.

He looked at the sky.

Still open. Still watching. The shapes behind it hadn’t moved.

The fluid was gone from his skin. Like it had never been there.

He felt different. He couldn’t have said how. Just that something small had shifted, somewhere underneath everything, the way a room feels different when someone has moved a piece of furniture while you were out. The same room. But not quite.

He looked at the machete in his hand.

First kill.

He’d thought it would feel like something specific. Horror or guilt or the particular numbness he’d read about. It felt like all three at once and also like nothing, which made no sense and also made complete sense.

His mother appeared in the gateway.

She looked at him. At the creature. At the fluid on his shirt.

She came to him and put one hand against his cheek the way she had when he was small and asked if he was hurt.

"No," he said.

She studied his face for a moment like she was checking if that was true.

Then she nodded once, and her hand dropped, and she turned back toward the hall and the people inside it who needed organizing.

Tobi looked at the empty street.

Somewhere in the distance, past the smoke and the screaming city, he heard new gates opening. Multiple, overlapping, the tearing sound of them layering over each other.

The night was just getting started.
